How is cyclopentolate and phenylephrine ophthalmic given?
cyclopentolate and phenylephrine ophthalmic is given as an eye drop placed into one or both eyes. A healthcare provider will place the drops in your eye.
Tell your doctor at once if you have severe burning, stinging, or irritation in your eyes.
After the drops are placed in your eye, gently press your finger to the inside corner of the eye for 2 to 3 minutes, to keep the liquid from draining into your tear duct. This will help prevent your body from absorbing too much of this medicine. Do not rub the eye.
If a child has been treated with this medicine, avoid allowing the child to rub or wipe the eyes. Closely watch the child for at least 30 minutes after the drops were placed in the eyes. This is to make sure the medicine does not cause any serious side effects by being absorbed through the tear duct.
Wash your hands after touching your eyes. If any of this medicine gets on a child's hands, wash them with soap and water. This will help prevent any medicine from accidentally reaching the child's mouth.
